Silver metal and gray rubber stethoscope with white ear pieces. Old, taped tag reads "Dr. Nicholson". Imprint on stethoscope reads "Littmann 3M Made in USA".
John N. Nicholson was a practicing doctor. He donated artifacts to the museum in the 2000s.
In the early 1960s a Harvard Medical School professor, cardiologist and recognized international authority on electrocardiography named Dr. David Littmann developed a new stethoscope with improved acoustic performance. Today, Littmann stethoscopes are still recognized for their acoustics. 3M acquired the stethoscope company on April 1, 1967, and hired Dr. Littmann as a consultant. 3M currently produces the range of Littmann brand stethoscopes.
